I need to establish which rear end the car has. Is there a code tag on the axle ?

I'd say a 8 3/4 ? Is that what you meant?

We call it a limited slip differential, here in England. Wondering whether it has one and what the ratio is ?

[JS29]

The standard ratio was 323's Sure grip was optional. Jack the rear of the car up so the tires are off the ground, have someone hold one side. if the other side turns freely it is not a limited slip. if it dose not turn freely it is a sure grip or limited slip.

Hi EV, how come the brake master cylinders are so sought after ? It it possible to re build them ?

It was only used on the 1970 Barracuda and Challenger (non-hemi engines) with disc brakes and then changed to a different part # for 1971-74.
Most were replaced over time and so remaining ones are few and far between, and highly sought after by anyone restoring one of these cars. So definitely don't get rid of it - they can be rebuilt but even the parts kits for them are getting harder to find.

Lots of info on these here on the forum, for example -

If you haven't already, look behind the back seat, under the front seats in the springs, and in behind the plastic seat-backs of the front seats for a build sheet. Chances are pretty good you'll find one and this sheet will have EVERYTHING you'd like to know about your car on it. You can use the decoders on this site to give you the breakdown on it all.

We took the seat backs off and Bingo, a Broadcast sheet in the passengers seat back! But.....it's for another Plum crazy SE, a 440 manual,  which was built Feb 18th 1970 so the line worker must have fitted the wrong broadcast sheet !!
My car has the correct SE seats.
